As Representatives of the several Underwriters listed in Schedule 1 hereto

Ladies and Gentlemen:

ArcelorMittal, a Luxembourg société anonyme (the “Company”), proposes to (i) issue and sell an aggregate of $1,250,000,000 principal amount of its 5.50% Mandatorily Convertible Subordinated Notes due 2023 (the “Notes”), and (ii) sell an aggregate of 80,906,149 common shares, without nominal value, of the Company (the “Shares”), each to the several Underwriters listed in Schedule 1 hereto (the “Underwriters”), for whom you are acting as representatives (the “Representatives”). The Notes and the Shares are herein referred to collectively as the “Securities.”

The Notes will be issued pursuant to an Indenture dated as of January 16, 2013, between the Company, Wilmington Trust, National Association, as trustee (the “Trustee”), and Citibank, N.A., as securities administrator (the “Securities Administrator”), as supplemented by a supplemental indenture thereto to be dated as of May 18, 2020 (as supplemented, the “Indenture”). The Notes will be mandatorily convertible into shares (the “Underlying Shares”) consisting of new and/or existing ordinary shares of the Company (the “Ordinary Shares”) in accordance with their terms and the terms of the Indenture. The non-U.S. or U.S., as the case may be, affiliates of the Representatives are set forth in Schedule 4 hereto.

The Company hereby confirms its agreement with the several Underwriters concerning the purchase and sale of the Securities, as follows:

1. Registration Statement. The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Securities Act”), a registration statement on Form F-3 (File No.

333-223400) including any post-effective amendments thereto, including a prospectus (the “Base Prospectus”), relating to the Securities and certain other debt and equity securities to be issued from time to time by the Company. The Company has also filed, or proposes to file, with the Commission pursuant to Rule 424 under the Securities Act prospectus supplements specifically relating to the Securities. The registration statement, as amended at the time it becomes effective, including the information, if any, deemed pursuant to Rule 430A, 430B or 430C under the Securities Act to be part of the registration statement at the time of its effectiveness, is referred to herein as the “Registration Statement”; and as used herein, the term “Prospectus” means the Base Prospectus as supplemented by the prospectus supplements specifically relating to the Securities in the form first used (or made available upon request of purchasers pursuant to Rule 173 under the Securities Act) in connection with confirmation of sales of the Securities and the term “Preliminary Prospectus” means the preliminary prospectus supplements specifically relating to the Securities together with the Base Prospectus. All references in this underwriting agreement (the “Agreement”) to financial statements and schedules and other information which is “given,” “contained,” “included,” “stated” or “described” in the Registration Statement, any Preliminary Prospectus or the Prospectus (or other references of like import) shall be deemed to mean and include all such financial statements and schedules and other information that are incorporated by reference in or otherwise deemed by the rules and regulations under the Securities Act to be a part of or included in the Registration Statement, any Preliminary Prospectus or the Prospectus, as the case may be; and all references in this Agreement to amendments or supplements to the Registration Statement, any Preliminary Prospectus or the Prospectus (or other references of like import) shall be deemed to mean and include the filing of any document under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), which is incorporated by reference in or otherwise deemed by the rules and regulations under Securities Act to be a part of or included in the Registration Statement, such Preliminary Prospectus or the Prospectus, as the case may be.

Capitalized terms used but not defined herein shall have the meanings given to such terms in the Registration Statement and the Prospectus. References herein to the Registration Statement, the Base Prospectus, any Preliminary Prospectus or Prospectus shall be deemed to refer to and include the documents incorporated by reference therein. For purposes of this Agreement, the term “Effective Time” means the effective date of the Registration Statement with respect to the offering of the Securities, as determined for the Company pursuant to Section 11 of the Securities Act and Item 512 of Regulation S-K, as applicable.

At or prior to the time when sales of Securities will first be made, the Company will prepare certain information, which will be identified in Schedule 2 hereto and which, together with the Preliminary Prospectus most recently used prior to the execution of this Agreement, constitute the “Time of Sale Information” for such offering of Securities. The “Time of Sale” is defined as 10:30 P.M., New York City time, on May 11, 2020.

2. Purchase of the Securities by the Underwriters. (a) The Company agrees to issue and sell the Notes to the several Underwriters as provided in this Agreement, and each Underwriter, on the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth herein, agrees, severally and not jointly, to purchase from the Company the respective principal amount of Notes set forth opposite such Underwriter’s name in Schedule 1 hereto at a price (the “Purchase Price”) equal to 99.08% of the principal amount thereof plus accrued interest, if any, from May 18, 2020 to the applicable Closing Date (as defined below). The Company will not be obligated to deliver any of the Notes except upon payment for all the Notes to be purchased as provided herein.

The Company agrees to issue and sell the Shares to the several Underwriters as provided in this Agreement, and each Underwriter, on the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth herein, agrees, severally and not jointly, to purchase from the Company the respective number of Shares set forth opposite such Underwriter’s name in Schedule 1 hereto at a price per share (the “Purchase Price”) of Euro 8.4957 or $9.1897 per Share, as applicable based on the split between allocations settled in Euros and Dollars, respectively, as notified in writing to the Company by the Representatives on behalf of the Underwriters as soon as practicable prior to the applicable Closing Date. The Company will not be obligated to deliver any of the Shares except upon payment for all the Shares to be purchased as provided herein.

The Company understands that the Underwriters intend to make a public offering of the Securities as soon after the effectiveness of this Agreement as in the judgment of the Representatives is advisable, and initially to offer the Securities on the terms set forth in the Time of Sale Information and the Prospectus. The Company

acknowledges and agrees that the Underwriters may offer and sell Securities to or through any affiliate of an Underwriter and that any such affiliate may offer and sell Securities purchased by it to or through any Underwriter.

(b) Payment for the Securities shall be made by wire transfer in immediately available funds to the account specified by the Company to the Representatives at the offices of Shearman & Sterling (London) LLP at 9:30 A.M., New York City time, on May 14, 2020 in respect of the Shares (the “Shares Closing Date”) and at 9:30 A.M., New York City time, on May 18, 2020 in respect of the Notes (the “Notes Closing Date” and, each of the Shares Closing Date and the Notes Closing Date, a “Closing Date”), or, in each case, at such other time or place on the same or such other date, not later than the fifth business day thereafter, as the Representatives and the Company may agree upon in writing.

Payment for the Securities to be purchased on the applicable Closing Date shall be made against delivery to the Representatives for the respective accounts of the several Underwriters of Shares, and, in respect of the Notes, one or more global notes (the “Global Notes”), with any transfer taxes payable in connection with the sale of such Securities duly paid by the Company. Delivery of the Notes and the Shares paid for in Dollars shall be made through the facilities of The Depository Trust Company (“DTC”); delivery of the Shares paid for in Euros shall be made through Euroclear Nederland; provided that delivery of shares to Lumen Investments S.à.▇.▇. (“Lumen”) will be of shares directly registered in the Luxembourg shareholders’ register. The Global Notes will be made available for inspection by the Representatives not later than 1:00 P.M., New York City time, on the business day prior to the Notes Closing Date.

(c) The Company acknowledges and agrees that the Underwriters are acting solely in the capacity of an arm’s length contractual counterparty to the Company with respect to the offering of Securities contemplated hereby (including in connection with determining the terms of the offering) and not as financial advisors or fiduciaries to, or agents of, the Company or any other person. Additionally, no such Underwriter is advising the Company or any other person as to any legal, tax, investment, accounting or regulatory matters in any jurisdiction. The Company shall consult with its own advisors concerning such matters and shall be responsible for making its own independent investigation and appraisal of the transactions contemplated hereby, and such Underwriters shall have no responsibility or liability to the Company with respect thereto. Any review by such Underwriters of the Company, the transactions contemplated thereby or other matters relating to such transactions will be performed solely for the benefit of the Underwriters and shall not be on behalf of the Company or any other person.

(i) As used in this Section 3(ee), “material subsidiary” means, at any time, a subsidiary of the Company whose gross assets or pre-tax profits (excluding intra-Group (as defined below) items) then equals or exceeds 5% of the gross assets or pre-tax profits of the Group. For this purpose: (1) the gross assets or pre-tax profits of a subsidiary of the Company will be determined from its financial statements (unconsolidated if it has subsidiaries) upon which the latest audited financial statements of the Group have been based; (2) if a company becomes a member of the Group after the date on which the latest audited financial statements of the Group have been prepared, the gross assets or pre-tax profits of that subsidiary will be determined from its latest financial statements; (3) the gross assets or pre-tax profits of the Group will be determined from its latest audited financial statements, adjusted (where appropriate) to reflect the gross assets or pre-tax profits of any company or business subsequently acquired or disposed of; and (4) if a material subsidiary disposes of all or substantially all of its assets to another subsidiary of the Company, it will immediately cease to be a material subsidiary and the other subsidiary (if it is not already) will immediately become a material subsidiary; the subsequent financial statements of those subsidiaries and the Group will be used to determine whether those subsidiaries are material subsidiaries or not. If there is a dispute as to whether or not a company is a material subsidiary, a certificate of the auditors of the Company will be, in the absence of manifest error, conclusive and binding on the Company and the Underwriters.

(ii) As used in this Section 3(ee), “subsidiary” means:

(1) an entity of which a person has direct or indirect control or owns directly or indirectly more than 50% of the voting capital or similar right of ownership (and control for this purpose means the power to direct the management and the policies of the entity whether through the ownership of voting capital, by contract or otherwise); and

(2) in relation to the Company, an entity which fulfils the definition in paragraph (i) above and which is included in the consolidated financial statements of the Company on a fully integrated basis.

(iii) As used in this Section 3(ee), the term “Group” means the Company and its subsidiaries that are included in the Company’s most recently published financial statements on a fully integrated basis.

(ff) No Unlawful Payments. Neither the Company nor any of its significant subsidiaries nor, to the knowledge of the Company, any director, officer or employee acting on behalf of the Company or any of its significant subsidiaries has (i) used any corporate funds for any unlawful contribution, gift, entertainment or other unlawful expense relating to political activity; (ii) made any direct or indirect unlawful payment to any foreign or domestic government official or employee from corporate funds; or (iii) violated or is in violation of any provision of the Foreign Corrupt Practices Act of 1977.

(gg) No Stabilization. The Company has not taken, directly or indirectly, any action designed to or that could reasonably be expected to cause or result in any stabilization or manipulation of the price of the Securities or the Ordinary Shares. The Company acknowledges that the Underwriters may engage in market making transactions in the Securities and Ordinary Shares in accordance with Regulation M under the Exchange Act.

(hh) ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act. There is and has been no material failure on the part of the Company or any of the Company’s directors or officers, in their capacities as such, to comply with any provision of the ▇▇▇▇▇▇▇▇-▇▇▇▇▇ Act of 2002 and the rules and regulations promulgated in connection therewith, including Section 402 related to loans and Sections 302 and 906 related to certifications.

(ii) No Restrictions or Withholding Taxes on Payments. There are no stamp or other issuance or transfer taxes or duties or other similar fees or charges required to be paid in Luxembourg or in the United States in connection with the execution and delivery of this Agreement, the Indenture, the issuance or sale of the Notes, and the sale of the Shares. Other than as described in the Time of Sale Information and the Prospectus, under the current laws and regulations of Luxembourg, all payments of principal, premium (if any) and interest on the Notes, and all dividends and distributions on the Shares, may be paid by the Company to the registered holder thereof in U.S. dollars (that may be obtained through conversion of the Euro) that may be freely transferred out of Luxembourg, and all such payments and other distributions made to holders of the Securities who are non-residents of Luxembourg and who have no permanent establishment nor permanent representative in Luxembourg to which the Notes are attributable will not be subject to Luxembourg income, withholding or other taxes under the laws and regulations of Luxembourg and are otherwise free and clear of any other tax, duty withholding or deduction in Luxembourg and without the necessity of obtaining any governmental authorization in Luxembourg.

(jj) Compliance with Money Laundering Laws. The operations of the Company, in its capacity as a non-financial institution, are and have at all times been, so far as the Company is aware, conducted in compliance with all material applicable financial recordkeeping and reporting requirements of the Money Laundering Laws (as defined below) and no action, suit or proceeding by or before any court or governmental agency, authority or body or any arbitrator involving the Company with respect to the Money Laundering Laws is pending, or, to the best of the Company’s knowledge, threatened, where “Money Laundering Laws” means the money laundering statutes of any jurisdiction in which the Company operates, the rules and regulations thereunder and any related or similar rules, regulations or guidelines, issued, administered or enforced by any governmental agency.

(e) Time of Sale Information. If at any time prior to the applicable Closing Date (i) any event shall occur or condition shall exist as a result of which any of the Time of Sale Information as then amended or supplemented would include any untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading or (ii) it is necessary to amend or supplement any of the Time of Sale Information to comply with applicable law, the Company will promptly notify the Underwriters thereof and promptly prepare and, subject to paragraph (b) above, furnish to the Underwriters such amendments or supplements to any of the Time of Sale Information as may be necessary so that the statements in any of the Time of Sale Information as so amended or supplemented will not, in light of the circumstances under which they were made, be misleading or so that any of the Time of Sale Information will comply with applicable law.

5. Certain Agreements of the Underwriters. Each Underwriter hereby represents and agrees that:

(a) It has not and will not use, authorize use of, refer to, or participate in the planning for use of, any “free writing prospectus,” as defined in Rule 405 under the Securities Act (which term includes use of any written information furnished to the Commission by the Company and not incorporated by reference into the Registration Statement) other than (i) a free writing prospectus that, solely as a result of use by such Underwriter, would not trigger an obligation to file such free writing prospectus with the Commission pursuant to Rule 433, (ii) any Issuer Free Writing Prospectus listed on Schedule 2 to this Agreement or prepared pursuant to Section 3(c) or Section 4(c) above (including any electronic road show), or (iii) any free writing prospectus prepared by such Underwriter and approved by the Company in advance in writing (each such free writing prospectus referred to in clauses (i) or (iii), an “Underwriter Free Writing Prospectus”).

(b) Notwithstanding the foregoing, the Underwriters may use term sheets substantially in the form of Schedule 3 to this Agreement without the consent of the Company.

(d) It has only communicated or caused to be communicated and will only communicate or cause to be communicated an invitation or inducement to engage in investment activity (within the meaning of Section 21 of the Financial Services and Markets ▇▇▇ ▇▇▇▇, or “FSMA”) received by it in connection with the issue or sale of the Securities which are the subject of the offering contemplated by the Prospectus in circumstances in which Section 21(1) of the FSMA does not apply to the Company.

(e) It has complied and will comply with all applicable provisions of the FSMA with respect to anything done by it in relation to the Securities in, from or otherwise involving the United Kingdom.

(f) In relation to each of the United Kingdom and each Member State of the European Economic Area (each, a “Relevant State”), it has not made and will not make an offer to the public of the Securities which are the subject of the offering contemplated by the Prospectus in that Relevant State (the “Offer Securities”), except that it may make an offer to the public of such Offer Securities in that Relevant State:

(i) at any time to any legal entity which is a qualified investor as defined in the Prospectus Regulation;

(ii) to fewer than 150 natural or legal persons (other than qualified investors as defined in the Prospectus Regulation), as permitted under the Prospectus Regulation, subject to obtaining the prior consent of the relevant underwriter or underwriters nominated by the Company for any such offer; or

(iii) at any time in any other circumstances falling within Article 1(4) of the Prospectus Regulation,

provided that no such offer of Offer Securities referred to in (i) to (iii) above shall require the Company or any Underwriter to publish a prospectus pursuant to Article 3 of the Prospectus Regulation or supplement a prospectus pursuant to Article 23 of the Prospectus Regulation.

For the purposes of this provision, the expression an “offer to the public” in relation to any Offer Securities in any Relevant State means the communication in any form and by any means of sufficient information on the terms of the offer and the Offer Securities to be offered so as to enable an investor to decide to purchase or subscribe the Offer Securities, and the expression “Prospectus Regulation” means Regulation (EU) 2017/1129 (as amended or superseded).

(b) Indemnification of the Company. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, and officers and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the indemnity set forth in paragraph (a) above, but only with respect to any duly documented losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to such Underwriter furnished to the Company in writing by or on behalf of such Underwriter through the Representatives expressly for use in the Registration Statement, the Prospectus (or any amendment or supplement thereto), any Issuer Free Writing Prospectus or any Time of Sale Information, it being understood and agreed that the only such information consists of the following information furnished on behalf of each Underwriter: (A) in the prospectus supplement included in the Preliminary Prospectus relating to the Shares, in the prospectus supplement to the Prospectus relating to the Shares, in the prospectus supplement included in the Preliminary Prospectus relating to the Notes and in the prospectus supplement to the Prospectus relating to the Notes: (i) the legal and marketing names of the Underwriters on the cover page and in the first paragraph and table under the heading “Underwriting,” (ii) the sub-paragraph “Price Stabilization, Short Positions” under the heading “Underwriting,” (iii) the first, second, third, and fourth paragraphs of the sub-paragraph “Other Relationships” under the heading “Underwriting,” and (iv) the sixth paragraph under the heading “Underwriting,” (B) in the prospectus supplement included in the Preliminary Prospectus relating to the Notes and in the prospectus supplement to the Prospectus relating to the Notes: (i) the first paragraph of the sub-paragraph “Commissions and Discounts” under the heading “Underwriting” and (ii) the second sentence of the sub-paragraph “New Issue of Notes” under the heading “Underwriting,” and (C) the legal and/or marketing names of the Underwriters in any Issuer Free Writing Prospectus (collectively, the “Underwriter Information”).

(c) Notice and Procedures. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to either paragraph (a) or (b) above, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under paragraph (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under paragraph (a) or (b) above. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified Person and any others entitled to indemnification pursuant to this Section 7 in such proceeding that the Indemnifying Person may designate and shall pay the fees and expenses of such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and reasonable and documented

expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to any local counsel) for all Indemnified Persons, and that all such fees and expenses shall be reimbursed as they are incurred. Any such separate firm for any Underwriter, its affiliates, directors and officers and any control persons of such Underwriter shall be designated in writing by the Representatives and any such separate firm for the Company, its directors and officers and any control persons of the Company shall be designated in writing by the Company. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 90 days after receipt by the Indemnifying Person of such request and (ii) (A) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement or (B) the Indemnifying Person shall not have, on or before the 90th day after the receipt by the Indemnifying Person of such request, disputed in good faith that the fees and expenses claimed by the Indemnified Person are payable by the Indemnifying Person hereunder. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or was threatened to be made a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

(d) Contribution. If the indemnification provided for in paragraphs (a) or (b) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and the Underwriters on the other from the offering of the Securities or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Company on the one hand and the Underwriters on the other in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company on the one hand and the Underwriters on the other shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Company from the sale of the Securities and the total discounts and commissions received by the Underwriters in connection therewith, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate offering price of the Securities. The relative fault of the Company on the one hand and the Underwriters on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) Limitation on Liability. The Company and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take

account of the equitable considerations referred to in paragraph (d) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of this Section 7, in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the total discounts and commissions received by such Underwriter with respect to the offering of the Securities exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to this Section 7 are several in proportion to their respective purchase obligations hereunder and not joint.

(f) Non-Exclusive Remedies. The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies that may otherwise be available to any Indemnified Person at law or in equity.

8. Termination. This Agreement may be terminated in the absolute discretion of the Representatives, by written notice to the Company, if after the execution and delivery of this Agreement and on or prior to the applicable Closing Date (i) trading generally shall have been suspended or materially limited on the New York Stock Exchange or the U.S. over-the-counter market, Euronext Amsterdam or Euronext Paris; (ii) trading of any securities issued or guaranteed by the Company shall have been suspended on any exchange or the U.S. over-the-counter market (other than as a result of exchange or market wide trading suspensions); (iii) a general moratorium on commercial banking activities shall have been declared by the authorities of any of the U.S. (federal or New York State), Luxembourg or France; or (iv) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States, that, in the reasonable judgment of the Representatives, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Securities on the terms and in the manner contemplated by this Agreement, the Time of Sale Information and the Prospectus.

9. Defaulting Underwriter. (a) If, on the applicable Closing Date, any Underwriter defaults on its obligation to purchase the Securities that it has agreed to purchase hereunder, the non-defaulting Underwriters may in their discretion arrange for the purchase of such Securities by other persons satisfactory to the Company on the terms contained in this Agreement. If, within 36 hours after any such default by any Underwriter, the non-defaulting Underwriters do not arrange for the purchase of such Securities, then the Company shall be entitled to a further period of 36 hours within which to procure other persons reasonably satisfactory to the non-defaulting Underwriters to purchase such Securities on such terms. If other persons become obligated or agree to purchase the Securities of a defaulting Underwriter, either the non-defaulting Underwriters or the Company may postpone the applicable Closing Date for up to five full business days in order to effect any changes that in the opinion of counsel for the Company and counsel for the Underwriters may be necessary in the Registration Statement and the Prospectus or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Registration Statement and the Prospectus that effects any such changes. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule 1 hereto that, pursuant to this Section 9, purchases Securities that a defaulting Underwriter agreed but failed to purchase.

(b) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the aggregate principal amount of Notes or the number of Shares that remains unpurchased does not exceed one-eleventh of the aggregate principal amount of all Notes or the number of Shares to be purchased on such date, respectively, then the Company shall have the right to require each non-defaulting Underwriter to purchase the principal amount of Notes or the number of Shares, as applicable, that such Underwriter agreed to purchase hereunder plus such Underwriter’s pro rata share (based on the principal amount of Notes or the number of Shares that such Underwriter agreed to purchase hereunder) of the Securities of such defaulting Underwriter or Underwriters for which such arrangements have not been made.

(c) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the aggregate principal amount of such Notes that remains unpurchased, or the number of Shares that remains unpurchased, as applicable, exceeds one-eleventh of the aggregate principal amount of all Notes or the number of Shares to be purchased on such date, as applicable, or if the Company shall not exercise the right described in paragraph (b) above, then this Agreement shall terminate without liability on the part of the non-defaulting Underwriters. Any termination of this Agreement pursuant to this Section 9 shall be without liability on the part of the Company, except that the Company will continue to be liable for the payment of expenses as set forth in Section 10 hereof and except that the provisions of Section 7 hereof shall not terminate and shall remain in effect.

(d) Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Company or any non-defaulting Underwriter for damages caused by its default.

10. Payment of Expenses. (a) Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, the Company agrees to pay or cause to be paid all reasonable and documented costs and expenses incident to the performance of its obligations hereunder, including without limitation, (i) the costs incident to the authorization, issuance, sale, preparation and delivery of the Securities and any taxes payable in connection therewith; (ii) the costs incident to the preparation, printing and filing under the Securities Act of the Registration Statement, the Preliminary Prospectus, any Issuer Free Writing Prospectus, any Time of Sale Information and the Prospectus (including any amendment or supplement thereto) and the distribution thereof; (iii) the costs of reproducing and distributing each of the Transaction Documents; (iv) the filing fees, if any, incurred in connection with the review and qualification of the offering of the Securities by the Financial Industry Regulatory Authority, Inc. (FINRA); (v) the fees and expenses of the Company’s counsel and independent accountants; (vi) any fees charged by rating agencies for rating or confirming the rating agency treatment of the Securities; (vii) the fees and expenses of the Trustee, the Securities Administrator, any registrar, and any paying or calculation agent (including related fees and expenses of any counsel to such parties); (viii) all expenses and application fees incurred in connection with any filing the approval of the Securities for book-entry transfer by DTC; and (ix) all expenses incurred by the Company in connection with any “road show” presentation to potential investors. For the sake of clarity, the Company shall not be obligated to pay, or cause to be paid, the fees of legal counsel to the Underwriters.

(b) If (i) the Company for any reason fails to tender the Securities for delivery to the Underwriters or (ii) the Underwriters decline to purchase the Securities for any reason permitted under this Agreement (other than as a result of termination of this Agreement pursuant to Section 8(i), (iii) or (iv)), the Company agrees to reimburse the Underwriters for all out-of-pocket reasonable and documented costs and expenses (including the fees and expenses of their counsel) reasonably incurred by the Underwriters in connection with this Agreement and the offering contemplated hereby.

11. Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and any controlling persons referred to herein, and the affiliates, officers and directors of each Underwriter referred to in Section 7 hereof. Nothing in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. No purchaser of Securities from any Underwriter shall be deemed to be a successor merely by reason of such purchase.

12. Survival. The respective indemnities, rights of contribution, representations, warranties and agreements of the Company and the Underwriters contained in this Agreement or made by or on behalf of the Company or the Underwriters pursuant to this Agreement or any certificate delivered pursuant hereto shall survive the delivery of and payment for the Securities and shall remain in full force and effect, regardless of any investigation made by or on behalf of the Company or the Underwriters. The provisions of Section 7 and Section 10 will survive the termination or cancellation of this Agreement.

(a) The Company irrevocably submits to the non-exclusive jurisdiction of any New York State or United States Federal court sitting in The City of New York, Borough of Manhattan, over any suit, action or proceeding arising out of or relating to this Agreement. The Company irrevocably waives, to the fullest extent permitted by law, any objection which it may now or hereafter have to the laying of venue of any such suit, action or proceeding brought in such a court and any claim that any such suit, action or proceeding brought in such a court has been brought in an inconvenient forum. To the extent that the Company has or hereafter may acquire any immunity (on the grounds of sovereignty or otherwise) from the jurisdiction of any court or from any legal process with respect to itself or its property, the Company irrevocably waives, to the fullest extent permitted by law, such immunity in respect of any such suit, action or proceeding.

(a) The Company hereby irrevocably appoints ArcelorMittal USA Holdings II LLC, ▇ ▇▇▇▇▇ ▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇ floor, ▇▇▇▇▇▇▇, ▇▇▇▇▇▇▇▇ ▇▇▇▇▇-▇▇▇▇, ▇▇▇▇▇▇ ▇▇▇▇▇▇, as its agent for service of process in any suit, action or proceeding described in the preceding paragraph and agrees that service of process in any manner permitted by applicable law in any such suit, action or proceeding may be made upon it at the office of such agent. The Company waives, to the fullest extent permitted by law, any other requirements of or objections to personal jurisdiction with respect thereto. The Company represents and warrants that such agent has agreed to act as its agent for service of process and agrees to take any and all action, including the filing of any and all documents and instruments that may be necessary to continue such appointment in full force and effect.

15. Judgment Currency. If for the purposes of obtaining judgment in any court it is necessary to convert a sum due hereunder into any currency other than United States dollars, the parties hereto agree, to the fullest extent permitted by law, that the rate of exchange used shall be the rate at which the Underwriters could purchase United States dollars with such other currency in The City of New York on the business day preceding that on which final judgment is given. The obligation of the Company with respect to any sum due from it to any Underwriter or any person controlling any Underwriter shall, notwithstanding any judgment in a currency other than United States dollars, not be discharged until the first business day following receipt by such Underwriter or controlling person of any sum in such other currency, and only to the extent that such Underwriter or controlling person may purchase United States dollars with such other currency. If the United States dollars so purchased are less than the sum originally due to such Underwriter or controlling person hereunder, the Company agrees, as a separate obligation and notwithstanding any such judgment, to indemnify such Underwriter or controlling person against such loss. If the United States dollars so purchased are greater than the sum originally due to such Underwriter or controlling person hereunder, such Underwriter or controlling person agrees to pay to the Company an amount equal to the excess of the dollars so purchased over the sum originally due to such Underwriter or controlling person hereunder.

Trade Date:		May 11, 2020

Interest Rate:		5.50% per annum

Interest Payment Dates:		February 18, May 18, August 18 and November 18 of each year, beginning on August 18, 2020, subject to deferral as described in the Preliminary Prospectus Supplement.

Interest Deferral:		Interest will be due and payable on each Interest Payment Date unless the Issuer elects not to pay such interest on such Interest Payment Date (which it may elect to do on any Interest Payment Date unless such Interest Payment Date is a Mandatory Interest Payment Date). Any such election not to pay interest shall not constitute a default of the Issuer, an Enforcement Event or any other breach of obligations under the Indenture or the Notes or for any other purpose. If the Issuer elects not to pay the interest on an Interest Payment Date, the Issuer will notify the Agents and the holders in accordance with the Indenture not less than ten and not more than 15 Business Days prior to the relevant Interest Payment Date. Any interest not paid because of such an election of the Issuer will constitute “Optionally Deferred Payments.” Optionally Deferred Payments shall themselves bear interest at the same interest rate borne by the Notes (the “Additional Interest Amount”). Additional Interest Amounts will accrue from the Interest Payment Date on which such amounts were initially deferred, and will be compounded on subsequent Interest Payment Dates, quarterly, at the then-applicable interest rate on the Notes. The nominal amount of any Optionally Deferred Payments together with any Additional Interest Amount shall constitute “Optionally Outstanding Payments.” The Issuer may pay outstanding Optionally Outstanding Payments (in whole but not in part) at any time upon giving not less than ten and not more than 15 Business Days’ notice to the holders in accordance with the Indenture (which notice will be irrevocable and will require the Issuer to pay the relevant Optionally Outstanding Payments on the payment date specified in such notice). All outstanding Optionally Outstanding Payments shall become due and payable (in whole but not in part) and shall be paid by the Issuer on any Mandatory Interest Payment Date.



Share Reference Price:		$9.27 per ordinary share of the Issuer (the public offering price in the Concurrent Share Offering).

Conversion Premium		Approximately 17.5% above the Minimum Conversion Price.

Adjustments:		Each Conversion Price and Conversion Ratio will be subject to adjustment upon the occurrence after the Issue Date of an Adjustment Event.

Minimum Conversion Price:		$9.27 per ordinary share of the Issuer (initially equal to the Share Reference Price).

Maximum Conversion Ratio:		2.69687 ordinary shares of the Issuer per $25 principal amount of the Notes, subject to adjustment.

Maximum Conversion Price:		$10.89 per ordinary share of the Issuer, subject to adjustment.

Minimum Conversion Ratio:		Initially 2.29521 ordinary shares of the Issuer per $25 principal amount of the Notes, subject to adjustment.

Initial Non-conversion Period:		Notwithstanding any other provision of the Notes, the Notes will not be convertible under any circumstances prior to July 28, 2020.

Ranking:		The obligations of the Issuer under the Notes constitute its direct, unsecured and subordinated obligations and will rank at all times pari passu without any preference or priority among themselves and will (subject to such exceptions as are from time to time mandatory under Luxembourg law) rank (a) in priority only to the rights and claims against the Issuer of the holders of Junior Securities; (b) pari passu with the rights and claims against the Issuer of the holders of any Parity Securities; and (c) junior to the rights and claims against the Issuer of the Issuer’s Senior Creditors. As of the Issue Date, there are no Parity Securities, and the only Junior Securities are the Shares.

Listing:		The Issuer will apply to list the Notes on the New York Stock Exchange (the “NYSE”), subject to satisfaction of the NYSE’s minimum equity listing standards with respect to the Notes. There can be no assurance that such requirement will be satisfied.

Mandatory Conversion on the Maturity Date:		Each Note not converted prior to the 25th Scheduled Trading Day immediately preceding the Maturity Date will be mandatorily converted on the Maturity Date into a number of Shares equal to the Relevant Conversion Ratio. On the Maturity Date, the Issuer will, in addition, pay any Optionally Outstanding Payments and any other accrued and unpaid interest to, but excluding, the Maturity Date.

Accelerated Mandatory Conversion:		Following the Initial Non-conversion Period, upon the occurrence of an Accelerated Mandatory Conversion Event prior to the 25th Scheduled Trading Day preceding the Maturity Date, the Issuer will notify the holders, the trustee and the securities administrator in accordance with the Indenture, and each $25 principal amount of outstanding Notes will be mandatorily converted into Shares at the then prevailing Maximum Conversion Ratio and the Issuer will pay a cash amount equal to the sum of (i) the Make-whole Amount, (ii) any Optionally Outstanding Payments, and (iii) any other accrued and unpaid interest.

Early Mandatory Conversion at the Option of the Issuer:		The Issuer may elect to cause the conversion of the Notes, in whole but not in part, into Shares at any time during the Conversion Period by giving not less than 30 and not more than 60 days’ advance notice, in which case each $25 principal amount of Notes will be mandatorily converted on the Optional Mandatory Conversion Date into such number of Settlement Shares as is equal to the Maximum Conversion Ratio. On the Settlement Date, the Issuer will, in addition, pay the Make-whole Amount, any Optionally Outstanding Payments and any other accrued and unpaid interest to, but excluding, the Settlement Date.

Voluntary Conversion Right of the Holder:		Each holder has the right to convert each of its Notes in whole or in part on any Business Day during the Conversion Period into a number of Settlement Shares equal to the Minimum Conversion Ratio. On the Settlement Date, the Issuer will, in addition, pay any Optionally Outstanding Payments in respect of the Notes being converted. Accrued and unpaid interest from, and including, the preceding Interest Payment Date, if any, to, but excluding, the conversion date will be deemed to have been paid in full rather than cancelled, extinguished or forfeited.

Voluntary Conversion upon the Occurrence of a Relevant Event:		Each holder who exercises its Voluntary Conversion Right during a Special Voluntary Conversion Period has the right to convert each of its Notes in whole or in part into Settlement Shares at the Relevant Event Conversion Ratio in the event of a Relevant Event after the Initial non-conversion Period and prior to the 25th Scheduled Trading Day preceding the Maturity Date, as described in the Preliminary Prospectus Supplement. On the Settlement Date, the Issuer will, in addition, pay the Make-whole Amount, any Optionally Outstanding Payments and any other accrued and unpaid interest to, but excluding, the Settlement Date, in each case in respect of the Notes being converted.



Make-whole Amount:		An amount per Note calculated by the Calculation Agent and equal to the approximate value of the embedded option right that has not yet been compensated for up to the relevant Settlement Date, calculated (and rounded to the nearest whole multiple of $0.01, with $0.005 being rounded upwards) pursuant to the following formula:

		c M = A x – t

		where: M = the Make-whole Amount; A = $3.74; c = the number of days from, and including, the relevant Settlement Date to, but excluding, the Maturity Date; and t = the number of days from, and including, the Issue Date to, but excluding, the Maturity Date.

Mittal Family Trust Participation:		Lumen Investments S.à ▇.▇., a company controlled by a Mittal Family Trust, is purchasing $100 million aggregate principal amount of Notes in the Notes Offering and $100 million aggregate principal amount of Shares in the Concurrent Share Offering at a public offering price of €8.57 per Share (corresponding to 10,787,487 Shares). Following the completion of the Notes Offering and the Concurrent Share Offering, Lumen Investments S.à ▇.▇. will own 35.6% of ArcelorMittal’s outstanding shares; assuming conversion of all Notes this percentage would be 32.6% (assuming conversion of all Notes at the Maximum Conversion Ratio) or 33.0% (assuming conversion of all Notes at the Minimum Conversion Ratio). The underwriters will not receive any discounts and commissions relating to the Shares and Notes purchased by Lumen Investments S.à ▇.▇.

Concurrent Share Offering:		Concurrently with the Notes Offering, the Issuer is offering 80,906,149 ordinary shares of the Issuer (the “Shares”) by means of a separate prospectus supplement and accompanying prospectus in an offering registered under the Securities Act (the “Concurrent Share Offering”). The net proceeds of the Concurrent Share Offering, after deduction of aggregate underwriting discounts and commissions and expenses of approximately $7.4 million, amount to approximately $742.6 million. BNP PARIBAS, Crédit Agricole CIB, ▇▇▇▇▇▇▇ ▇▇▇▇▇ & Co. LLC, ▇.▇. ▇▇▇▇▇▇ and Société Générale, the global coordinators and joint bookrunners of the Notes Offering, will act as the global coordinators and joint bookrunners for the Concurrent Share Offering, and BBVA, BofA Securities, COMMERZBANK, HSBC, ING, Mizuho International plc, Natixis and UniCredit, joint bookrunners of the Notes Offering, will act as joint bookrunners for the Concurrent Share Offering. The Notes Offering is not contingent upon the completion of the Concurrent Share Offering, and the Concurrent Share Offering is not contingent upon the Notes Offering.

Redemption upon a Shareholder Event:		It is anticipated that the Issuer will not initially have sufficient Shares available through standing corporate authorization and Shares in treasury available to satisfy all its Share delivery obligations upon conversion of the Notes after giving effect to the Concurrent Share Offering and other outstanding Share delivery obligations. The Issuer intends to convene a general meeting of shareholders where a resolution (the “Shareholder Resolution”) will be proposed to approve sufficient authorized capital for the issuance of the maximum number of Shares potentially deliverable upon conversion of the Notes. If the Shareholder Resolution is not passed by July 28, 2020 (the “Resolution Deadline”), the Issuer may, by giving notice (the “Shareholder Event Notice”) not later than the 10th Trading Day after the Resolution Deadline (the “Shareholder Event Notice Period”), elect to redeem all but not some only of the Notes at the greater of (i) 102% of the principal amount of the Notes, together with accrued interest and (ii) 102% of the Fair Note Value of the Notes together with accrued interest, whereupon the Notes will be redeemed, on the day falling three Trading Days after the end of the Fair Note Value Calculation Period. If the Shareholder Resolution is not passed by the Resolution Deadline, the Initial Non-Conversion Period will be automatically extended through (1) the expiration of the Shareholder Event Notice Period, or (2) the redemption of the Notes, if the Issuer exercises such right.

Accounting Treatment:		The principal amount of the Notes issued will be allocated according to IAS 32.31 between financial liabilities and equity taking into consideration transaction costs. In case of the conversion of any Note there will be a transfer between additional paid-in capital and share capital in the amount of the notional value of the issued shares.

Lock-Up:		180 days from the date of the final prospectus supplement.

The Issuer has filed a registration statement (including a prospectus) with the Securities and Exchange Commission (the “SEC”) for the Notes Offering to which this communication relates. Before you invest, you should read the Preliminary Prospectus Supplement and the accompanying prospectus in that registration statement and other documents the Issuer has filed with the SEC for more complete information about the Issuer and the Notes Offering. You may get these documents for free by visiting ▇▇▇▇▇ on the SEC web site at ▇▇▇.▇▇▇.▇▇▇. Alternatively, copies may be obtained from ▇▇▇▇▇▇▇ Sachs & Co. LLC by calling toll-free ▇▇-▇▇▇-▇▇▇-▇▇▇▇.

It is expected that delivery of the Notes will be made against payment therefor on or about May 18, 2020, which is the fifth business day following the trade date for the offering (such settlement cycle being referred to as “T+5”). Under Rule 15c6-1 under the Exchange Act, trades in the secondary market generally are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the Notes on the date hereof or the next two succeeding business days will be required, by virtue of the fact that the Notes initially will settle in T+5, to specify an alternative cycle at the time of any such trade to prevent failed settlement. Purchasers of the Notes who wish to trade the Notes prior to the second business day before settlement should consult their own advisors.

Re: ArcelorMittal - Lock-Up Agreement

Ladies and Gentlemen:

The undersigned understands that you, as representatives (the “Representatives”), propose to enter into an Underwriting Agreement on behalf of the several Underwriters named in Schedule 1 to such agreement (the “Underwriters”), with ArcelorMittal, a Luxembourg société anonyme (the “Company”), providing for the offering by the Company of (i) $1,250,000,000 principal amount of its 5.50% Mandatorily Convertible Subordinated Notes (the “Convertible Notes”) and (ii) an aggregate of 80,906,149 ordinary shares, without nominal value, of the Company (the “Underwritten Shares”). The Convertible Notes will be mandatorily convertible into new or existing ordinary shares of the Company (the “Ordinary Shares”).

The Convertible Notes and the Underwritten Shares will be registered pursuant to a Registration Statement filed with the Securities and Exchange Commission (the “SEC”).

In consideration of the agreement by the Underwriters to offer and sell the Convertible Notes and the Underwritten Shares, and of other good and valuable consideration the receipt and sufficiency of which is hereby acknowledged, the undersigned agrees that, during the period specified in the following paragraph (the “Lock-Up Period”), the undersigned will not offer, sell, contract to sell, pledge, grant any option to purchase, make any short sale or otherwise dispose of any Ordinary Shares, or any options or warrants to purchase any Ordinary Shares, or any securities convertible into, exchangeable for or that represent the right to receive Ordinary Shares, whether now

owned or hereinafter acquired, whether owned directly by the undersigned (including holding as a custodian) or with respect to which the undersigned has beneficial ownership within the rules and regulations of the SEC (collectively the “Undersigned’s Shares”). The foregoing restriction is expressly agreed to preclude the undersigned from engaging in any hedging or other transaction that is designed to or that reasonably could be expected to lead to or result in a sale or disposition of the Undersigned’s Shares even if such Ordinary Shares would be disposed of by someone other than the undersigned. Such prohibited hedging or other transactions would include without limitation any short sale or any purchase, sale or grant of any right (including without limitation any put or call option) with respect to any of the Undersigned’s Shares or with respect to any security that includes, relates to, or derives any significant part of its value from such Ordinary Shares.

The initial Lock-Up Period will commence on the date of this Lock-Up Agreement and continue for 180 days after the public offering date set forth on the final prospectus used to sell the Convertible Notes and the Underwritten Shares (the “Public Offering Date”) pursuant to the Underwriting Agreement.

Notwithstanding the foregoing, the undersigned may transfer the Undersigned’s Shares (i) as a bona fide gift or gifts, provided that the donee or donees thereof agree to be bound in writing by the restrictions set forth herein, (ii) to any trust for the direct or indirect benefit of Mr. and Mrs. ▇▇▇▇▇▇▇ ▇▇▇▇▇▇ or the immediate family of Mr. and Mrs. ▇▇▇▇▇▇▇ ▇▇▇▇▇▇, or to any company wholly owned, whether directly or indirectly, by any such trust, provided that the trustee of the trust or the wholly owned company, as the case may be, agrees to be bound in writing by the restrictions set forth herein, and provided further that any such transfer shall not involve a disposition for value, or (iii) with the prior written consent of the Representatives on behalf of the Underwriters. For purposes of this Lock-Up Agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin. In addition, notwithstanding the foregoing, if the undersigned is a corporation, the corporation may transfer the Ordinary Shares to any wholly-owned subsidiary of such corporation; provided, however, that in any such case, it shall be a condition to the transfer that the transferee execute an agreement stating that the transferee is receiving and holding such Ordinary Shares subject to the provisions of this Lock-Up Agreement and there shall be no further transfer of such Ordinary Shares except in accordance with this Lock-Up Agreement, and, provided further, that any such transfer shall not involve a disposition for value.

In addition, notwithstanding the foregoing, this Lock-Up Agreement will not apply to (i) any transfer of the Undersigned’s Shares in the context of a restructuring of the structure through which trusts benefitting the Mittal family hold, directly or indirectly, Ordinary Shares, provided that each such affiliate transferee shall execute and deliver to the Representatives acting on behalf of the Underwriters a lock-up agreement in which it agrees to be bound by the restrictions set forth herein for the Lock-Up Period, (ii) any transfer of the Undersigned’s Shares or other securities (a) in connection with a public tender or exchange offer for the shares of the Company within the scope of the Luxembourg law of 19 May 2006 concerning public takeovers (loi du 19 mai 2006 concernant les offres publiques d’acquisition) or (b) in the context and in consideration of any merger or acquisition of assets, provided that in the case of (b) each such transferee shall execute and deliver to the Representatives acting on behalf of the Underwriters a lock-up agreement in which it agrees to be bound by the restrictions set forth herein for the Lock-Up Period, (iii) any pledge or granting of other type of security over the Undersigned’s Shares in connection with financing transactions or facilities to which the undersigned or any entity controlled by the undersigned (a) is a party as of the date hereof and/or (b) becomes a party hereafter, provided in the case of (b) that the beneficiary of such pledge or other security interest undertakes to the Underwriters to retain the Undersigned’s Shares that are the subject of such pledge or other security interest for the Lock-Up Period, or (iv) any pledge or granting of other type of security over the Undersigned’s Shares in connection with financing transactions or facilities to which the undersigned is a party and which finances the acquisition of Ordinary Shares or Convertible Notes in the public offering referred to above.

The undersigned understands that the Company and the Underwriters are relying upon this Lock-Up Agreement in proceeding toward consummation of the offering of the Convertible Notes and Underwritten Shares. The undersigned further represents and warrants that the undersigned has full power and authority to enter into this Lock-Up Agreement, and understands that this Lock-Up Agreement is irrevocable and shall be binding upon the undersigned’s heirs, legal representatives, successors, and assigns.

Very truly yours,
